The Browns plan to sign cornerback Terrance Mitchell to a three-year, $12 million contact, a person familiar with the situation confirmed Wednesday.

ESPN first reported the move.

He'll reunite with new Browns General Manager John Dorsey.

Mitchell cannot sign the contract until free agency officially starts at 4 p.m. Wednesday.

The Browns need help at cornerback, where Jason McCourty and Jamar Taylor were the starters last season. They traded for Damarious Randall last week but plan to use him as a free safety after he spent the past three seasons playing cornerback for the Green Bay Packers.

Mitchell, 25, spent the past two seasons with the Kansas City Chiefs and started nine of his 15 games last season, compiling 53 tackles and 18 passes defensed, including four interceptions.

When Dorsey was the GM of the Chiefs, they signed Mitchell to their practice squad on Sept. 6, 2016.

The Dallas Cowboys drafted Mitchell in the seventh round (No. 254 overall) out of Oregon in 2014. He appeared in eight combined games with the Chicago Bears and Cowboys before joining the Chiefs.

Mitchell, 5-foot-11 and 190 pounds, has started 11 of the 30 games in which he has appeared and compiled 85 tackles, with one sack, plus 27 passes defensed, including five interceptions, and a forced fumble. All of his starts have been with the Chiefs.
